Function classification and subcellular localization analysis of DEPs
Function classification and subcellular localization predication were conducted to demonstrate these DEPs in biological process level and cellular component level. As shown in Figure 3A, the majority of these DEPs were involved in photosynthesis (23.0%), carbohydrate metabolism/energy production (23.0%) and nitrogen assimilation/protein metabolism (20.3%), followed by redox homeostasis and stress response (14.8%), cell structure and division (8.1%) and secondary metabolism (4.0%). Other protein groups included signal transduction and Ca homeostasis (1.4%) and unknown protein (5.4%).
